What Is Cephalic Position?

The ideal fetal position for labor and delivery

• Why It's Best

Risks of Other Positions

• Determining Position
• Turning a Fetus

The cephalic position is when a fetus is head down when it is ready to enter the birth canal. This is one of a few variations of how a fetus can rest in the womb and is considered the ideal one for labor and delivery.

About 96% of babies are born in the cephalic position. Most settle into it between the 32nd and 36th weeks of pregnancy . Your healthcare provider will monitor the fetus's position during the last weeks of gestation to ensure this has happened by week 36.

If the fetus is not in the cephalic position at that point, the provider may try to turn it. If this doesn't work, some—but not all—practitioners will attempt to deliver vaginally, while others will recommend a Cesarean (C-section).

Why Is the Cephalic Position Best?

During labor, contractions dilate the cervix so the fetus has adequate room to come through the birth canal. The cephalic position is the easiest and safest way for the baby to pass through the birth canal.

If the fetus is in a noncephalic position, delivery becomes more challenging. Different fetal positions have a range of difficulties and varying risks.

A small percentage of babies present in noncephalic positions. This can pose risks both to the fetus and the mother, and make labor and delivery more challenging. It can also influence the way in which someone can deliver.

A fetus may actually find itself in any of these positions throughout pregnancy, as the move about the uterus. But as they grow, there will be less room to tumble around and they will settle into a final position.

It is at this point that noncephalic positions can pose significant risks.

Cephalic Posterior

A fetus may also present in an occiput or cephalic posterior position. This means they are positioned head down, but they are facing the abdomen instead of the back.

This position is also nicknamed "sunny-side up."

Presenting this way increases the chance of a painful and prolonged delivery.

There are three different types of breech fetal positioning:

• Frank breech: The legs are up with the feet near the head.
• Footling breech: One or both legs is lowered over the cervix.
• Complete breech: The fetus is bottom-first with knees bent.

A vaginal delivery is most times a safe way to deliver. But with breech positions, a vaginal delivery can be complicated.

When a baby is born in the breech position, the largest part—its head—is delivered last. This can result in them getting stuck in the birth canal (entrapped). This can cause injury or death.

The umbilical cord may also be damaged or slide down into the mouth of the womb, which can reduce or cut off the baby's oxygen supply.

Some providers are still comfortable performing a vaginal birth as long as the fetus is doing well. But breech is always a riskier delivery position compared with the cephalic position, and most cases require a C-section.

Likelihood of a Breech Baby

You are more likely to have a breech baby if you:

• Go into early labor before you're full term
• Have an abnormally shaped uterus, fibroids , or too much amniotic fluid
• Are pregnant with multiples
• Have placenta previa (when the placenta covers the cervix)

Transverse Lie

In transverse lie position, the fetus is presenting sideways across the uterus rather than vertically. They may be:

• Down, with the back facing the birth canal
• With one shoulder pointing toward the birth canal
• Up, with the hands and feet facing the birth canal

If a transverse lie is not corrected before labor, a C-section will be required. This is typically the case.

Determining Fetal Position

Your healthcare provider can determine if your baby is in cephalic presentation by performing a physical exam and ultrasound.

In the final weeks of pregnancy, your healthcare provider will feel your lower abdomen with their hands to assess the positioning of the baby. This includes where the head, back, and buttocks lie

If your healthcare provider senses that the fetus is in a breech position, they can use ultrasound to confirm their suspicion.

Turning a Fetus So They Are in Cephalic Position

External cephalic version (ECV) is a common, noninvasive procedure to turn a breech baby into cephalic position while it's still in the uterus.

This is only considered if a healthcare provider monitors presentation progress in the last trimester and notices that a fetus is maintaining a noncephalic position as your delivery date approaches.

External Cephalic Version (ECV)

ECV involves the healthcare provider applying pressure to your stomach to turn the fetus from the outside. They will attempt to rotate the head forward or backward and lift the buttocks in an upward position. Sometimes, they use ultrasound to help guide the process.

The best time to perform ECV is about 37 weeks of pregnancy. Afterward, the fetal heart rate will be monitored to make sure it’s within normal levels. You should be able to go home after having ECV done.

ECV has a 50% to 60% success rate. However, even if it does work, there is still a chance the fetus will return to the breech position before birth.

Natural Methods For Turning a Fetus

There are also natural methods that can help turn a fetus into cephalic position. There is no medical research that confirms their efficacy, however.

• Changing your position: Sometimes a fetus will move when you get into certain positions. Two specific movements that your provider may recommend include: Getting on your hands and knees and gently rocking back and forth. Another you could try is pushing your hips up in the air while laying on your back with your knees bent and feet flat on the floor (bridge pose).
• Playing stimulating sounds: Fetuses gravitate to sound. You may be successful at luring a fetus out of breech position by playing music or a recording of your voice near your lower abdomen.
• Chiropractic care: A chiropractor can try the Webster technique. This is a specific chiropractic analysis and adjustment which enables chiropractors to establish balance in the pregnant person's pelvis and reduce undue stress to the uterus and supporting ligaments.
• Acupuncture: This is a considerably safe way someone can try to turn a fetus. Some practitioners incorporate moxibustion—the burning of dried mugwort on certain areas of the body—because they believe it will enhance the chances of success.

A Word From Verywell

While most babies are born in cephalic position at delivery, this is not always the case. And while some fetuses can be turned, others may be more stubborn.

This may affect your labor and delivery wishes. Try to remember that having a healthy baby, and staying well yourself, are your ultimate priorities. That may mean diverting from your best laid plans.

Speaking to your healthcare provider about turning options and the safest route of delivery may help you adjust to this twist and feel better about how you will move ahead.

• Pregnancy week by week
• Fetal presentation before birth

The way a baby is positioned in the uterus just before birth can have a big effect on labor and delivery. This positioning is called fetal presentation.

Babies twist, stretch and tumble quite a bit during pregnancy. Before labor starts, however, they usually come to rest in a way that allows them to be delivered through the birth canal headfirst. This position is called cephalic presentation. But there are other ways a baby may settle just before labor begins.

Following are some of the possible ways a baby may be positioned at the end of pregnancy.

Head down, face down

When a baby is head down, face down, the medical term for it is the cephalic occiput anterior position. This the most common position for a baby to be born in. With the face down and turned slightly to the side, the smallest part of the baby's head leads the way through the birth canal. It is the easiest way for a baby to be born.

Head down, face up

When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.

Most babies who begin labor in this position eventually turn to be face down. If that doesn't happen, and the second stage of labor is taking a long time, a member of the health care team may reach through the vagina to help the baby turn. This is called manual rotation.

In some cases, a baby can be born in the head-down, face-up position. Use of forceps or a vacuum device to help with delivery is more common when a baby is in this position than in the head-down, face-down position. In some cases, a C-section delivery may be needed.

Frank breech

When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head. This is the most common type of breech presentation.

If you are more than 36 weeks into your pregnancy and your baby is in a frank breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Most babies in a frank breech position are born by planned C-section.

Complete and incomplete breech

A complete breech presentation, as shown below, is when the baby has both knees bent and both legs pulled close to the body. In an incomplete breech, one or both of the legs are not pulled close to the body, and one or both of the feet or knees are below the baby's buttocks. If a baby is in either of these positions, you might feel kicking in the lower part of your belly.

If you are more than 36 weeks into your pregnancy and your baby is in a complete or incomplete breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Many babies in a complete or incomplete breech position are born by planned C-section.

When a baby is sideways — lying horizontal across the uterus, rather than vertical — it's called a transverse lie. In this position, the baby's back might be:

• Down, with the back facing the birth canal.
• Sideways, with one shoulder pointing toward the birth canal.
• Up, with the hands and feet facing the birth canal.

Although many babies are sideways early in pregnancy, few stay this way when labor begins.

If your baby is in a transverse lie during week 37 of your pregnancy, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of your health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a transverse lie, talk with a member of your health care team about the choices you have for delivery. Many babies who are in a transverse lie are born by C-section.

If you're pregnant with twins and only the twin that's lower in the uterus is head down, as shown below, your health care provider may first deliver that baby vaginally.

Then, in some cases, your health care team may suggest delivering the second twin in the breech position. Or they may try to move the second twin into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

Your health care team may suggest delivery by C-section for the second twin if:

• An attempt to deliver the baby in the breech position is not successful.
• You do not want to try to have the baby delivered vaginally in the breech position.
• An attempt to move the baby into a head-down position is not successful.
• You do not want to try to move the baby to a head-down position.

In some cases, your health care team may advise that you have both twins delivered by C-section. That might happen if the lower twin is not head down, the second twin has low or high birth weight as compared to the first twin, or if preterm labor starts.

Why Is Cephalic Presentation Ideal For Childbirth?

5   Dec   2017 | 8 min Read

During labour, contractions stretch your birth canal so that your baby has adequate room to come through during birth. The cephalic presentation is the safest and easiest way for your baby to pass through the birth canal.

If your baby is in a non-cephalic position, delivery can become more challenging. Different fetal positions pose a range of difficulties and varying risks and may not be considered ideal birthing positions.

Two Kinds of Cephalic Positions

There are two kinds of cephalic positions:

• Cephalic occiput anterior , where your baby’s head is down and is facing toward your back.
• Cephalic occiput posterior , where your baby is positioned head down, but they are facing your abdomen instead of your back. This position is also nicknamed ‘sunny-side-up’ and can increase the chances of prolonged and painful delivery. 

How to Know if Your Baby is In a Cephalic Position?

You can feel your baby’s position by rubbing your hand on your belly. If you feel your little one’s stomach in the upper stomach, then your baby is in a cephalic position. But if you feel their kicks in the lower stomach, then it could mean that your baby is in a breech position.

You can also determine whether your baby is in the anterior or posterior cephalic position. If your baby is in the anterior position, you may feel their movement underneath your ribs and your belly button could also pop out. If your baby is in the posterior position, then you may feel their kicks in their abdomen, and your stomach may appear rounded up instead of flat. 

You can also determine your baby’s position through an ultrasound scan or a physical examination at your healthcare provider’s office. 

Benefits of Cephalic Presentation in Pregnancy

Cephalic presentation is one of the most ideal birth positions, and has the following benefits:

• It is the safest way to give birth as your baby’s position is head-down and prevents the risk of any injuries.
• It can help your baby move through the delivery canal as safely and easily as possible.
• It increases the chances of smooth labour and delivery.

Are There Any Risks Involved in Cephalic Position?

Conditions like a cephalic posterior position in addition to a narrow pelvis of the mother can increase the risk of pregnancy complications during delivery. Some babies in the head-first cephalic presentation might have their heads tilted backward. This may, in some rare cases, cause preterm delivery.

What are the Risks Associated with Other Birth Positions?

A small percentage of babies may settle into a non-cephalic position before their birth. This can pose risks to both your and your baby’s health, and also influence the way in which you deliver. 

In the next section, we have discussed a few positions that your baby can settle in throughout pregnancy, as they move around the uterus. But as they grow old, there will be less space for them to tumble around, and they will settle into their final position. This is when non-cephalic positions can pose a risk.  

Breech Position

There are three types of breech fetal positioning:

• Frank breech : Your baby’s legs stick straight up along with their feet near their head.
• Footling breech: One or both of your baby’s legs are lowered over your cervix.
• Complete breech: Your baby is positioned bottom-first with their knees bent.

If your baby is in a breech position , vaginal delivery is considered complicated. When a baby is born in breech position, the largest part of their body, that is, their head is delivered last. This can lead to injury or even fetal distress. Moreover, the umbilical cord may also get damaged or get wrapped around your baby’s neck, cutting off their oxygen supply.  

If your baby is in a breech position, your healthcare provider may recommend a c-section, or they may try ways to flip your baby’s position in a cephalic presentation.

Transverse Lie

In this position, your baby settles in sideways across the uterus rather than being in a vertical position. They may be:

• Head-down, with their back facing the birth canal
• One shoulder pointing toward the birth canal
• Up with their hands and feet facing the birth canal

If your baby settles in this position, then your healthcare provider may suggest a c-section to reduce the risk of distress in your baby and other pregnancy complications.

Turning Your Baby Into A Cephalic Position

External cephalic version (ECV) is a common, and non-invasive procedure that helps turn your baby into a cephalic position while they are in the womb. However, your healthcare provider may only consider this procedure if they consider you have a stable health condition in the last trimester, and if your baby hasn’t changed their position by the 36th week.

You can also try some natural remedies to change your baby’s position, such as:

• Lying in a bridge position: Movements like bridge position can sometimes help move your baby into a more suitable position. Lie on your back with your feet flat on the ground and your legs bent. Raise your pelvis and hips into a bridge position and hold for 5-10 minutes. Repeat several times daily.
• Chiropractic care: A chiropractor can help with the adjustment of your baby’s position and also reduce stress in them.
• Acupuncture: After your doctor’s go-ahead, you can also consider acupuncture to get your baby to settle into an ideal birthing position.

While most babies settle in a cephalic presentation by the 36th week of pregnancy, some may lie in a breech or transverse position before birth. Since the cephalic position is considered the safest, your doctor may recommend certain procedures to flip your baby’s position to make your labour and delivery smooth. You may also try the natural methods that we discussed above to get your baby into a safe birthing position and prevent risks or other pregnancy complications. 

When Should A Baby Be In A Cephalic Position?

Your baby would likely naturally drop into a cephalic position between weeks 37 to 40 of your pregnancy .

Is Cephalic Position Safe?

Research shows that 95% of babies take the cephalic position a few weeks or days before their due date. It is considered to be the safest position. It ensures a smooth birthing process.

While most of the babies are in cephalic position at delivery, this is not always the case. If you have a breech baby, you can discuss the available options for delivery with your doctor.

Does cephalic presentation mean labour is near?

Head-down is the ideal position for your baby within your uterus during birth. This is known as the cephalic position. This posture allows your baby to pass through the delivery canal more easily and safely.

Can babies change from cephalic to breech?

The external cephalic version (ECV) is the most frequent procedure used for turning a breech infant.

How can I keep my baby in a cephalic position?

While your baby naturally gets into this position, you can try some exercises to ensure that they settle in cephalic presentation. Exercises such as breech tilt, forward-leaning position (spinning babies program), cat and camel pose can help.

28 Weeks Pregnant Ultrasound

28 Weeks Baby Movement

Your baby is starting to take up more and more space, and will soon settle into a head-down position (or cephalic presentation) for labor and birth. Most babies are fully head-down between 32 and 36 weeks of pregnancy. But others may take a little longer, need some coaxing by your healthcare provider to get there or never end up head-down, in which case, a c-section is likely.

Now that you’re in the third trimester, you’re about to lose more of your precious energy. It’s no wonder—your baby is getting bigger, and it can be tough to get comfortable enough to get a good night’s sleep.

28 Weeks Pregnant Symptoms

The third trimester is here! And while that means you’re getting closer to baby’s arrival, it also means you might be starting to feel less comfortable. Here’s what you can expect.

Frequent urination

The need to pee all the time may return now that baby’s big enough to crowd your bladder.

Your growing baby is also putting pressure on your stomach and intestines, making heartburn a strong possibility. Try to prevent it by avoiding spicy and greasy foods, and other foods you notice bother you. “Keep a food journal to pinpoint which foods trigger you the most,” says Al Bradlea, a lactation consultant and birth and postpartum doula. “Some usual culprits are spicy and fried foods, coffee and chocolate.” Also avoid lying down within an hour of eating, and try to eat smaller meals more often—five or six mini meals, instead of three big meals, for example. “Sleep on a slight incline,” adds Bradlea. But think twice before popping an OTC remedy. “If it gets to the point where you’re in pain after every meal despite your best efforts, talk to your doctor—especially before trying antacids, some of which aren’t safe for pregnancy,” says Bradlea.

Over two thirds of pregnant people experience back pain , and with good reason: a bigger baby changes your posture and strains your spine. Not to mention the fact that hormonal changes are relaxing your ligaments, which can make you less stable while on the move.

Even worse than run-of-the-mill back pain? Feeling tingling, numbness or shooting pain through your lower back, butt and thighs. These are symptoms of sciatica —it gets its weird name from the sciatic nerve, which runs from the lower back and branches down both legs. It can happen during pregnancy because the growing uterus puts pressure on the nerve—and bloating, weight gain and posture changes don’t help either. Try a warm compress wherever you feel pain, remember to rest and add pelvic tilts to your Kegels routine to help strengthen your core. “When in doubt, get into child’s pose —and then, seek extra help to build strength and show your body some love,” says Bradlea.

Braxton Hicks contractions

Look out for sporadic tightening of your belly as your body preps for labor and birth. Braxton Hicks contractions are different from true labor contractions because they’re not regular and go away fairly quickly. The real deal would intensify in frequency, coming more and more often and more intensely.

Restless leg syndrome (RLS)

About 16 percent of pregnant people simply can’t keep their legs still at night. “People are sometimes surprised that after another exhausting day of pregnancy, they can get into bed and have Restless Leg Syndrome!” says Bradlea. RLS can make you antsy and really mess with your ability to get sleep. Talk to your doctor about taking a supplement if you have RLS—magnesium, iron, B12 or folate could help. Stretch and massage your legs, using a heating pad or warm bath or try ice to relieve symptoms. “Incorporating some movement into your routine is the first step. You don’t need hours of intense aerobics—an evening stroll for a half hour can provide immense relief,” says Bradlea.

More appointments

This technically isn’t a symptom, but it is a fact of pregnancy at this stage: In the third trimester, your OB or midwife is going to become your new best friend (if they aren’t already). At 28 weeks, you’ll have two appointments per month (every other week), and by 36 weeks pregnant , you’ll be going weekly.

Pregnancy Symptoms Coming Up In Week 29:

In week 29 of pregnancy, some common symptoms can include constipation, lightheadedness or UTIs.

Only 4% of babies are born on their predicted due date. But about 90% are born within two weeks before or after—which means baby’s birthday is narrowed down to about a full month.

Commonly Asked Questions About 28 Weeks Pregnant

Once you hit the third trimester, the final countdown is on. Give your growing belly a rub and check out these commonly asked questions with month seven just around the corner.

How can I sneak in some fun before baby arrives?

Sometime in the next 14 weeks, life is about to get a lot more hectic. Use your final trimester to sneak in some extra fun. Schedule a few date nights, plan some visits with friends, get your nails done and head to your favorite coffee shop for a leisurely latte as often as you can.

What are the benefits of red raspberry leaf tea?

The purported benefits of red raspberry leaf tea are many, but studies have shown that the herb can actually help reduce the length of labor and help birthing parents avoid extra interventions. Check with your healthcare provider, then start with a cup a day of 100% red raspberry leaf rather than a blend. FYI: The tea doesn’t actually taste like raspberries—sorry!—but you won’t have to hold your nose to get it down.

What’s a good way to pass the time while 28 weeks pregnant?

For some people, pregnancy is a race to the finish line. For others, the weeks can really drag. If you fall into the latter camp, now’s a great time to start binging a long-running series. Try Friends or The Office for laughs, and Scandal or The Sopranos for drama and suspense. For feel-good vibes, you can’t go wrong with The Great British Baking Show . Don’t worry if you’ve already seen it before; what matters is it keeps your mind occupied and the hours flying by.

How can I prep for postpartum chaos?

If your budget allows, consider a night nurse to help in those first few weeks. These experienced individuals, also called postpartum doulas or night nannies, come to your home at the end of the day and care for your baby all night long, so you can, you know, sleep like a baby. If you’re nursing, they’ll wake you for a feeding, but afterward, the baby goes straight back into their care. Some night nurses even do your laundry and wash your dishes. The downside is that this extra help comes at a cost. Do your research to compare rates—and remember, even one night a week can make a noticeable difference. You could also add it to your baby registry—it could make a great baby shower group gift.

Your baby in the birth canal

During labor and delivery, your baby must pass through your pelvic bones to reach the vaginal opening. The goal is to find the easiest way out. Certain body positions give the baby a smaller shape, which makes it easier for your baby to get through this tight passage.

The best position for the baby to pass through the pelvis is with the head down and the body facing toward the mother's back. This position is called occiput anterior.

Information

Certain terms are used to describe your baby's position and movement through the birth canal.

FETAL STATION

Fetal station refers to where the presenting part is in your pelvis.

• The presenting part. The presenting part is the part of the baby that leads the way through the birth canal. Most often, it is the baby's head, but it can be a shoulder, the buttocks, or the feet.
• Ischial spines. These are bone points on the mother's pelvis. Normally the ischial spines are the narrowest part of the pelvis.
• 0 station. This is when the baby's head is even with the ischial spines. The baby is said to be "engaged" when the largest part of the head has entered the pelvis.
• If the presenting part lies above the ischial spines, the station is reported as a negative number from -1 to -5.

In first-time moms, the baby's head may engage by 36 weeks into the pregnancy. However, engagement may happen later in the pregnancy, or even during labor.

This refers to how the baby's spine lines up with the mother's spine. Your baby's spine is between their head and tailbone.

Your baby will most often settle into a position in the pelvis before labor begins.

• If your baby's spine runs in the same direction (parallel) as your spine, the baby is said to be in a longitudinal lie. Nearly all babies are in a longitudinal lie.
• If the baby is sideways (at a 90-degree angle to your spine), the baby is said to be in a transverse lie.

FETAL ATTITUDE

The fetal attitude describes the position of the parts of your baby's body.

The normal fetal attitude is commonly called the fetal position.

• The head is tucked down to the chest.
• The arms and legs are drawn in towards the center of the chest.

Abnormal fetal attitudes include a head that is tilted back, so the brow or the face presents first. Other body parts may be positioned behind the back. When this happens, the presenting part will be larger as it passes through the pelvis. This makes delivery more difficult.

DELIVERY PRESENTATION

Delivery presentation describes the way the baby is positioned to come down the birth canal for delivery.

The best position for your baby inside your uterus at the time of delivery is head down. This is called cephalic presentation.

• This position makes it easier and safer for your baby to pass through the birth canal. Cephalic presentation occurs in about 97% of deliveries.
• There are different types of cephalic presentation, which depend on the position of the baby's limbs and head (fetal attitude).

If your baby is in any position other than head down, your doctor may recommend a cesarean delivery.

Breech presentation is when the baby's bottom is down. Breech presentation occurs about 3% of the time. There are a few types of breech:

• A complete breech is when the buttocks present first and both the hips and knees are flexed.
• A frank breech is when the hips are flexed so the legs are straight and completely drawn up toward the chest.
• Other breech positions occur when either the feet or knees present first.

The shoulder, arm, or trunk may present first if the fetus is in a transverse lie. This type of presentation occurs less than 1% of the time. Transverse lie is more common when you deliver before your due date, or have twins or triplets.

CARDINAL MOVEMENTS OF LABOR

As your baby passes through the birth canal, the baby's head will change positions. These changes are needed for your baby to fit and move through your pelvis. These movements of your baby's head are called cardinal movements of labor.

• This is when the widest part of your baby's head has entered the pelvis.
• Engagement tells your health care provider that your pelvis is large enough to allow the baby's head to move down (descend).
• This is when your baby's head moves down (descends) further through your pelvis.
• Most often, descent occurs during labor, either as the cervix dilates or after you begin pushing.
• During descent, the baby's head is flexed down so that the chin touches the chest.
• With the chin tucked, it is easier for the baby's head to pass through the pelvis.

Internal Rotation

• As your baby's head descends further, the head will most often rotate so the back of the head is just below your pubic bone. This helps the head fit the shape of your pelvis.
• Usually, the baby will be face down toward your spine.
• Sometimes, the baby will rotate so it faces up toward the pubic bone.
• As your baby's head rotates, extends, or flexes during labor, the body will stay in position with one shoulder down toward your spine and one shoulder up toward your belly.
• As your baby reaches the opening of the vagina, usually the back of the head is in contact with your pubic bone.
• At this point, the birth canal curves upward, and the baby's head must extend back. It rotates under and around the pubic bone.

External Rotation

• As the baby's head is delivered, it will rotate a quarter turn to be in line with the body.
• After the head is delivered, the top shoulder is delivered under the pubic bone.
• After the shoulder, the rest of the body is usually delivered without a problem.

Fetal Presentation, Position, and Lie (Including Breech Presentation)

• Key Points |

Abnormal fetal lie or presentation may occur due to fetal size, fetal anomalies, uterine structural abnormalities, multiple gestation, or other factors. Diagnosis is by examination or ultrasonography. Management is with physical maneuvers to reposition the fetus, operative vaginal delivery , or cesarean delivery .

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for transverse presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

Predisposing factors for breech presentation include

Preterm labor

Uterine abnormalities

Fetal anomalies

If delivery is vaginal, breech presentation may increase risk of

Umbilical cord prolapse

Birth trauma

Perinatal death

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor. Operative vaginal delivery or cesarean delivery is often required.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

You and your baby at 32 weeks pregnant

Your baby at 32 weeks.

By about 32 weeks, the baby is usually lying with their head pointing downwards, ready for birth. This is known as cephalic presentation.

If your baby is not lying head down at this stage, it's not a cause for concern – there's still time for them to turn.

The amount of amniotic fluid in your uterus is increasing, and your baby is still swallowing fluid and passing it out as urine.

Breech, posterior, transverse lie: What position is my baby in?

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. At the time of delivery, 97 percent of babies are head-down (cephalic presentation). But there are several other possibilities, including feet or bottom first (breech) as well as sideways (transverse lie) and diagonal (oblique lie).

Fetal presentation and position

During the last trimester of your pregnancy, your provider will check your baby's presentation by feeling your belly to locate the head, bottom, and back. If it's unclear, your provider may do an ultrasound or an internal exam to feel what part of the baby is in your pelvis.

Fetal position refers to whether the baby is facing your spine (anterior position) or facing your belly (posterior position). Fetal position can change often: Your baby may be face up at the beginning of labor and face down at delivery.

Here are the many possibilities for fetal presentation and position in the womb.

Medical illustrations by Jonathan Dimes

Head down, facing down (anterior position)

A baby who is head down and facing your spine is in the anterior position. This is the most common fetal presentation and the easiest position for a vaginal delivery.

This position is also known as "occiput anterior" because the back of your baby's skull (occipital bone) is in the front (anterior) of your pelvis.

Head down, facing up (posterior position)

In the posterior position , your baby is head down and facing your belly. You may also hear it called "sunny-side up" because babies who stay in this position are born facing up. But many babies who are facing up during labor rotate to the easier face down (anterior) position before birth.

Posterior position is formally known as "occiput posterior" because the back of your baby's skull (occipital bone) is in the back (posterior) of your pelvis.

Frank breech

In the frank breech presentation, both the baby's legs are extended so that the feet are up near the face. This is the most common type of breech presentation. Breech babies are difficult to deliver vaginally, so most arrive by c-section .

Some providers will attempt to turn your baby manually to the head down position by applying pressure to your belly. This is called an external cephalic version , and it has a 58 percent success rate for turning breech babies. For more information, see our article on breech birth .

Complete breech

A complete breech is when your baby is bottom down with hips and knees bent in a tuck or cross-legged position. If your baby is in a complete breech, you may feel kicking in your lower abdomen.

Incomplete breech

In an incomplete breech, one of the baby's knees is bent so that the foot is tucked next to the bottom with the other leg extended, positioning that foot closer to the face.

Single footling breech

In the single footling breech presentation, one of the baby's feet is pointed toward your cervix.

Double footling breech

In the double footling breech presentation, both of the baby's feet are pointed toward your cervix.

Transverse lie

In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than 1 percent of the time, but it happens more commonly if you're carrying multiples or deliver before your due date.

If your baby stays in a transverse lie until the end of your pregnancy, it can be dangerous for delivery. Your provider will likely schedule a c-section or attempt an external cephalic version , which is highly successful for turning babies in this position.

Oblique lie

In rare cases, your baby may lie diagonally in your uterus, with his rump facing the side of your body at an angle.

Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie at the end of your third trimester.

What are the indications and contraindications to external cephalic version (ECV)?

What are the success rates of ECV?

What are the key steps to the procedure?

What are the risks associated with ECV?

Mrs. Smith is a 27-y.o. G2P0010 at 37 0/7 weeks gestation who was sent to you by her primary obstetrician for ECV after discovery of breech presentation at her 36-week appointment. The patient has many questions regarding the intended procedure, and as the OB/GYN hospitalist who will be performing the ECV, you must be prepared to answer her.

Malpresentation (i.e. noncephalic presentation) complicates approximately 5% of pregnancies at term. 1 Diagnosis is typically made by ultrasound, preferably before the onset of labor. Although abdominal palpation or vaginal exam may suggest malpresentation, the diagnosis should be confirmed by ultrasound. The American College of Obstetricians and Gynecologists (ACOG) recommends documentation of fetal presentation starting at 36 weeks gestation. 2 If malpresentation is identified and no contraindications exist, the obstetrician should offer the patient ECV and counsel her on the risks and benefits of the procedure. In ECV, the obstetrician attempts to turn the fetus manually into a cephalic presentation. ACOG has recently published a Practice Bulletin that summarizes the major points and evidence with regard to ECV. 2

Breech presentation occurs in 3% to 4% of labors. 1 It is more common earlier in gestation, with 25% of pregnancies <28 weeks and 7% of pregnancies at 32 weeks being complicated by breech presentation. 1 There are three types of breech presentation: frank, complete, and incomplete (also known as footling ) ( Fig. 63-1 ). Factors associated with breech presentation include such fetal malformations as trisomies, prematurity, müllerian anomalies, and fundal placentation. 1 As experience with breech vaginal deliveries ( Chapter 59 ) is declining, most women with a breech fetus deliver by cesarean section (C-section) ( Chapter 60 ). Alternatively, ECV may be employed to turn the fetus and permit a vaginal delivery. Of note, ECV also should be offered in cases of transverse and oblique lies, and it has a higher success rate in these circumstances than in breech presentation. 2

All women with singleton fetuses in nonvertex presentations at term should be offered a trial of ECV unless contraindications exist. Box 63-1 lists the indications for ECV.

• Continuing Education Activity

In carefully selected patients, an external cephalic version (ECV) may be an alternative to cesarean delivery for fetal malpresentation at term. ECV is a noninvasive procedure that manipulates fetal position through the abdominal wall of the gravida. With the global cesarean section rate reaching 34%, fetal malpresentation ranks as the third most common indication for cesarean delivery, accounting for nearly 17% of cases. Studies suggest a 60% mean success rate for ECV, emphasizing its cost-effectiveness and potential to decrease cesarean delivery rates significantly. While particularly crucial in resource-limited settings where access to medical services during labor is constrained or cesarean delivery is unavailable or unsafe, ECV presents a viable option to improve rates of vaginal delivery in singleton gestations in all settings. 

This activity reviews the indications, contraindications, necessary equipment, preferred personnel, procedural technique, risks, and benefits of ECV and highlights the role of the interprofessional team in caring for patients who may benefit from this procedure.

• Select suitable candidates for an external cephalic version based on their clinical history and presentation.
• Screen patients effectively regarding the risks and benefits of an external cephalic version.
• Apply best practices when performing an external cephalic version.
• Develop and implement effective interpersonal team strategies to improve outcomes for patients undergoing external cephalic version.
• Introduction

The global cesarean section rate has increased from approximately 23% to 34% in the past decade. Fetal malpresentation is now the third-most common indication for cesarean delivery, encompassing nearly 17% of cases. Almost one-fourth of all fetuses are in a breech presentation at 28 weeks gestational age; this number decreases to between 3% and 4% at term. In current clinical practice, most pregnancies with a breech fetus are delivered by cesarean section.

Individual and institutional efforts are increasing to reduce the overall cesarean delivery rate, particularly for nulliparous patients with term, singleton, and vertex gestations. [1] [2]  An alternative to cesarean delivery for fetal malpresentation at term is an external cephalic version (ECV), a procedure to correct fetal malpresentation. ECV may be indicated when the fetus is breech or in an oblique or transverse lie after 37 0/7 weeks gestation. [3]  The overall success rate for ECV approaches 60%, is cost-effective, and can lead to decreased cesarean delivery rates. [4]  ECV is of particular importance in resource-poor environments, where patients may have limited access to medical services during labor and delivery or where cesarean delivery is unavailable or unsafe.

• Anatomy and Physiology

ECV can be attempted when managing breech presentations or fetuses with a transverse or oblique lie. Three types of breech presentation are established concerning fetal attitude: complete, frank, and incomplete, which is sometimes referred to as footling breech. In complete breech, the fetal pelvis engages with the maternal pelvic inlet, and the fetal hips and knees are flexed. In frank breech, the fetal pelvis engages with the maternal pelvic inlet, the fetal hips are flexed, the knees are extended, and the feet are near the head. In incomplete or footling breech, one (single footling) or both (double footling) feet are extended below the level of the fetal pelvis.

A fetus with a transverse lie is positioned with their long axis, defined as the spine, at a right angle to the long axis of the gravida. The fetal head may be to the right or left side of the maternal spine. The fetus may be facing up or down. The long axis of the fetus characterizes an oblique lie at any angle to the maternal long axis that is not 90°. An oblique fetus is usually positioned with their head in the right or left lower quadrants, although this is not universal.

• Indications

ECV may be indicated in carefully selected patients. The fetus must be at or beyond 36 0/7 weeks of gestation with malpresentation, and there must be no absolute contraindications to vaginal delivery, such as placenta previa, vasa previa, or a history of classical cesarean delivery. Fetal status must be reassuring, and preprocedural nonstress testing is recommended. While ECV may be performed as early as 36 0/7 weeks gestation, many practitioners will delay ECV until 37 0/7 weeks gestation to ensure delivery of a term fetus.

ECV is more successful in multigravidas, those with a complete breech or transverse or oblique presentation, an unengaged presenting part, adequate amniotic fluid, and a posterior placenta. Nulliparous patients and those with an anterior, lateral, or cornual placenta have lower success rates. Patients with advanced cervical dilatation, obesity, oligohydramnios, or ruptured membranes also have lower success rates. Additionally, if the fetus weighs less than 2500 g, is at a low station with an engaged presenting part, is frank breech, or the spine is posterior, the success of ECV is decreased. [5]  

Evidence supports the use of parenteral tocolysis, most often with the beta-2-agonist medication terbutaline, to improve the success of ECV; most studies evaluating the various aspects of ECV aspects include using a tocolytic agent. [6] [7] [8] [9]  Data regarding the improved success of ECV incorporating regional anesthesia is inconsistent. 

• Contraindications

Any contraindication to vaginal delivery would also be a contraindication to ECV. These contraindications include but are not limited to placenta previa, vasa previa, active genital herpes outbreak, or a history of classical cesarean delivery. A history of low transverse cesarean delivery is not an absolute contraindication to ECV. [10]  The overall success rate of ECV in patients with a previous cesarean birth ranges from 50% to 84%; no cases of uterine rupture during ECV were reported in the four trials evaluating this outcome in patients with a prior cesarean delivery. [11] [12] [13] [14]

Antepartum ECV is contraindicated in multiple gestations, although it can be utilized for twin gestations that would otherwise be suitable candidates for breech extraction. [15] [16]

Patients with severe oligohydramnios, nonreassuring fetal monitoring, a hyperextended fetal head, significant fetal or uterine anomaly, fetal growth restriction, and maternal hypertension carry a low likelihood of successful ECV and a significantly increased risk of poor fetal outcomes; ECV in such situations requires careful consideration.

If a gravida who is otherwise a suitable candidate for ECV presents in early labor with fetal malpresentation, ECV may be a reasonable option if the presenting part is unengaged, the amniotic fluid index is within the normal range, and there are no contraindications to ECV or vaginal delivery. Data from the Nationwide Inpatient Sample from 1998 to 2011 noted a success rate of 65% for ECV performed in carefully selected patients during the admission for delivery. [17]  ECV performed in this circumstance resulted in a significantly lower cesarean birth rate and hospital stay of greater than 7 days compared to patients with a persistent breech presentation at the time of delivery. [17]

External cephalic versions should be attempted only in settings where cesarean delivery services are readily available. Therefore, the required equipment for ECV includes all such requirements for cesarean delivery, including anesthesia services. Access to tocolytic agents, bedside ultrasonography, and external fetal heart rate monitoring equipment is also required. Following ECV, fetal status must be assessed; nonstress testing is preferred. If nonstress testing is unavailable, Doppler indices of the umbilical artery, middle cerebral artery, and ductus venosus may be performed. [18]

The personnel typically required to perform an ECV include:

• Obstetrician
• Labor and delivery nurse.

ECV may only be performed in a setting where cesarean delivery services are readily available. Personnel typically required for cesarean delivery include:

• Surgical first assistant
• Anesthesia personnel
• Surgical technician or operating room nurse
• Circulating or operating room nurse
• Pediatric personnel
• Note: for cesarean delivery, labor and delivery nurses may serve as surgical technicians, circulating, or operating room roles.
• Preparation

Before attempting ECV, informed consent must be obtained; this should include tocolysis and neuraxial analgesia if those procedures will be performed. Some clinicians will obtain consent from the patient for potential emergency cesarean delivery at this time, although this practice is not universal. Additionally, an ultrasound examination should be performed to verify fetal presentation, exclude fetal and uterine anomalies, locate the placental position, and evaluate the amniotic fluid index. Many clinicians will evaluate preprocedural fetal status with a nonstress test. 

The current evidence supports the administration of terbutaline 0.25mg subcutaneously 15 to 30 minutes before the ECV but does not support using calcium channel blockers or nitroglycerin for preprocedural tocolysis. [19]  While multiple studies report the increased success of ECV in patients who are administered epidural or spinal neuraxial anesthesia, overall data is insufficient to warrant a universal recommendation; neuraxial anesthesia may improve success rates for ECV in situations where tocolysis alone was unsuccessful. [20]

• Technique or Treatment

The gravida should be supine with a leftward tilt using a wedge support to relieve pressure on the great vessels. ECV is best performed using a 2-handed approach.

If the fetal presentation is breech, lift the breech out of the pelvis with one hand and apply downward pressure to the posterior fetal head to attempt a forward roll. If a forward roll is unsuccessful, a backward roll can be attempted. If the fetus is in either a transverse or oblique presentation, similar manipulation of the fetus is used to try to move the fetal head to the pelvis. [21]

Fetal well-being should be evaluated intermittently with Doppler or real-time ultrasonography during ECV. ECV should be abandoned if there is significant fetal bradycardia, patient discomfort, or if a version is not achieved easily. After a successful or unsuccessful ECV, external fetal heart rate monitoring should be performed for 30 to 60 minutes. If the gravida is Rh negative, anti-D immune globulin should be administered.

Immediate induction of labor to minimize reversion is not recommended. If the initial attempt at ECV is unsuccessful, additional attempts can be made during the same admission or at a later date.

• Complications

Complications of ECV are rare and occur in only 1% to 2% of attempts. The most common complication associated with ECV is fetal heart rate abnormalities, particularly bradycardia, occurring at a rate of 4.7% to 20%; these abnormalities usually are transient and improve upon completion or abandonment of the procedure.

More severe complications of ECV occur at a rate of less than 1% and include premature rupture of membranes, cord prolapse, vaginal bleeding, placental abruption, fetomaternal hemorrhage, emergent cesarean delivery, and stillbirth. Many of these rare complications require emergent cesarean delivery; some clinicians choose to perform ECV in the operating room, although this is neither necessary nor universal. [22]   

ECV is associated with changes in Doppler indices that may reflect decreased placental perfusion. It appears these changes are short-lived and have no detrimental effects on the outcomes of uncomplicated pregnancies. A recent prospective study investigating the effects of ECV on fetal circulation in the antepartum period noted no differences in the Doppler evaluation of the middle cerebral artery or ductus venosus; all studied patients remained stable and were discharged home after the procedure. [18]  

• Clinical Significance

Some data indicate that only 20% to 30% of eligible candidates are offered ECV. [23]  Patients who undergo a successful ECV procedure have a lower cesarean delivery rate than patients who do not but are still at a higher risk of cesarean delivery than patients with cephalic fetuses who do not require ECV. ECV is cost-effective if the probability of a successful ECV exceeds 32%. Overall, ECV is successful in 58% of attempts, reduces the risk for CS by two-thirds, and enables 80% of these patients to deliver vaginally. [24]

• Enhancing Healthcare Team Outcomes

ECV is not a benign procedure and is most successful when performed under the care of an interprofessional team. Labor and delivery nurses play an integral role in the success of ECV as they frequently assist in the procedure, prepare the patient for ECV, and implement external fetal monitoring before, during, and after the procedure. Additionally, the support of emergent operating room staff promotes the safe delivery of a healthy fetus should complications arise during the ECV procedure. Clear and concise anticipatory interprofessional communication improves safety and outcomes for the gravida and the fetus should complications occur.

What is Memorial Day? The true meaning of why we celebrate the federal holiday

For many Americans, Memorial Day is more than a long weekend and an unofficial start to the summer season. The real meaning of the holiday is meant to honor all U.S. soldiers who have died serving their country.

Originally called Decoration Day, Memorial Day's history goes back to the Civil War. It was was declared a national holiday by Congress in 1971, according to the U.S. Department of Veterans' Affairs.

Although Veterans Day in November also honors military service members, Memorial Day differs by honoring all military members who have died while serving in U.S. forces in any current or previous wars.

The late-May holiday has also evolved into an opportunity for Americans to head to the beach or lake , travel to see friends and family , or even catch a Memorial Day parade .

Here's what to know about the history and the reason behind why we observe Memorial Day.

When is Memorial Day?

One of 11 federal holidays recognized in the U.S., Memorial Day is always observed on the last Monday of May. This year, the holiday falls on Monday, May 27.

Why do we celebrate Memorial Day?  

The origins of the holiday can be traced back to local observances for soldiers with neglected gravesites during the Civil War.

The first observance of what would become Memorial Day, some historians think, took place in Charleston, South Carolina at the site of a horse racing track that Confederates had turned into a prison holding Union prisoners. Blacks in the city organized a burial of deceased Union prisoners and built a fence around the site, Yale historian David Blight wrote in  The New York Times  in 2011.

Then on May 1, 1865, they held an event there including a parade – Blacks who fought in the Civil War participated – spiritual readings and songs, and picnicking. A commemorative marker was erected there in 2010.

One of the first Decoration Days was held in Columbus, Mississippi, on April 25, 1866 by women who decorated graves of Confederate soldiers who perished in the battle at Shiloh with flowers. On May 5, 1868, three years after the end of the Civil War, the tradition of placing flowers on veterans’ graves was continued by the establishment of Decoration Day by an organization of Union veterans, the Grand Army of the Republic. 

General Ulysses S. Grant presided over the first large observance, a crowd of about 5,000 people, at Arlington National Cemetery in Virginia on May 30, 1873.

This tradition continues to thrive in cemeteries of all sizes across the country. 

Until World War I, Civil War soldiers were solely honored on this holiday. Now, all Americans who’ve served are observed. 

At least 25 places in the North and the South claim to be the birthplace of Memorial Day. Some states that claim ownership of the origins include Illinois, Georgia, Virginia, and Pennsylvania, according to Veterans Affairs.

Despite conflicting claims, the U.S. Congress and President Lyndon Johnson declared Waterloo, New York, as the “birthplace” of Memorial Day on May 30, 1966, after Governor Nelson Rockefeller's declaration that same year. The New York community formally honored local veterans May 5, 1866 by closing businesses and lowering flags at half-staff. 

Why is Memorial Day in May? 

The day that we celebrate Memorial Day is believed to be influenced by Illinois U.S. Representative John A. Logan, who was elected to the U.S. House of Representatives as a Democrat in November 1858, and served as an officer during the Mexican War.

It is said that Logan, a staunch defender of the Union, believed Memorial Day should occur when flowers are in full bloom across the country, according to the  National Museum of the U.S. Army.

Congress passed an act making May 30 a holiday in the District of Columbia in 1888,  according to the U.S. Congressional Research Service.

In 2000, the National Moment of Remembrance Act – which created the White House Commission on the National Moment of Remembrance and encourages all to pause at 3 p.m. local time on Memorial Day for a minute of silence – was signed into law by Congress and the President.

What is the difference between Memorial Day and Veterans Day?

Memorial Day and Veterans Day both honor the sacrifices made by U.S. veterans, but the holidays serve different purposes.

Veterans Day, originally called “Armistice Day,” is a younger holiday established in 1926 as a way to commemorate all those who had served in the U.S. armed forces during World War I.

Memorial Day honors all those who have died.
